Title: Data encoding method and data decoding method
Inventor: SHIMPUKU YOSHIHIDE
IPC: G11B20/14
Filed: 1995-12-12
Abstract: A data encoding method for converting a (m   i) bit based data word string into a (n   i) bit based codeword string. The encoding method receives a (m   i) bit based data word string by a shift register 1, decides a constraint length specifying the length of a data word which is to be converted by an encoder 2, and decides on which number of bits as counted from the leading end of the m bits falls the leading end bit of the data word which is to be converted. The encoding method selects, by a selector 3, one of a plurality of conversion tables constituting variable length tables and at least satisfying the minimum run length d, in accordance with the constraint length and the above results of decision. The encoding method also generates a codeword corresponding to the data word,  now to be  converted,  in accordance with   the  selected conversion table. The encoding method assures a larger value of the product of the minimum length between transitions and the window margin, thus enabling data to be recorded to a higher density on an information recording medium.

The screw (10) includes a shank (18) with a tip end and a head end. A head (22) at the head end may be driven by a driving tool such as a pneumatic or electric drill. To facilitate retention of the washer (16) the head (22) has a flange (32) that forms a recess (34). The shank (18) has an enlarged portion (28) near the head (22) adjacent to the recess (34) and the enlarged portion (28) has ridges (30). The enlarged portion (28), including the ridges (30), increases the driving resistance of the screw (10). This increase in resistance gives notice to an operator of the driving tool that an appropriate driving depth and torque have been achieved. Preferably, the washer (16) has an inner diameter surface (42) with fully radiused projections (44). The projections (44) assist in mounting the washer (16) to the screw (10) and keeping the washer (16) appropriately positioned on the screw (10) during storage and driving. <IMAGE>
